I only have three same-age opponents, same as when PvP began. At first I felt bad hitting them as often as I did but they are in the same position because I am only getting attacked by the same three players. Doing the math makes be feel better. I win battles with same-age players and score 280 points. They attack me and I lose 140 points. The best part is that I can hit them 12 times a day in total (without buying attempts) and earn 3,360 points but the system limits my losses to 5 per day for a total of 700 points, Net net, without buying attempts and excluding attempt rewards, my score rises by 2,260 a day (79,800 per month which is diamond league). Add in purchased attempts and reaching crystal league is not hard.
